PPDS

[Former Member]

Hi Friends,

The PPDS horizon is 7 days as of today. Tomorrow it should be 6 days and day after it should be 5 daya. Then the next day it has to be 7 days again. Is there any standard way of doing it in SAP PPDS? Pls help.

Hi Shruthi,

One method could be setting SNP production horizon as 1 calendar week (period type W if your week starts with Monday or W0 for week starting on Sunday) and PP/DS production horizon as blank. The system, by default, considers the SNP production horizon as PP/DS production horizon.

For instance, with period type W0, the production horizon is from Sunday through Saturday. Considering today as Wednesday, the production horizon is 4 days, tomorrow it will be 3 days, and so on.

Thanks,

Thanks Rajesh,

But is there any other way apart from changing masterdata. Pls advice.

Shruthi,

As per my knowledge, PPDS horizon is related to master data that can't be dynamically set by standard PPDS functionality. If you think of using this varying horizon with just one or two heuristics without touching master data, probably, you can use custom heuristics that are modeled off from the existing ones.

If you could throw some more light, it would be helpful to understand the context and suggest something useful to you.

Thanks,

Hi Rajesh,

The requirement is just to fix the ppds horizon for 7 days on monday and 6 days on tuesday and so on. Can we use planning interval heuristic for this? thinking to test it. Here we can make the planning interval as 1 week. so anything outside will be scheduled out of the planning interval.its kind of planning time fence. Any suggestion?

Hi Shruthi,

You may try using lot sizing heuristic SAP_PP_004 (with just short-term lot) with period type lot size procedure (t.code /sapapo/cdpsc11 and tab lot size). Please check the documentation of the heuristic for details.

Set your period type as week and number of periods 1. From the start of the heuristic, the algorithm considers all the demand for one week (in the same as you want with decremental number of days) to calculate the net requirements.

In this way, you need not to consider the production horizon.

Thanks,

Hi

Easy way to do it is make PPDS horizon to 'ZERO' days in product Master. So

1. for SNP to PPDS order conversion, you can developed a program which will update SAP_SNP_SNGL - Individual Conversion SNP --> PP/DS in Offset for the Conversion Horizon field. So before execution of this heuristics, you execute this program which will update the offset as per your requirement which will in turn will add offset to PP/DS horizon.

2. if you want to execute PP/DS planning run, check for Scheduling offset period in strategy tab of the respective heuristics i.e. e.g. SAP_PP_002.. so again execute the program with required horizon which will add valued to this offset and will add value to PP/DS horizon..

Test this.. it will work...
